It was a little less than three and half years into the six year development program for the completely redesigned 7-series luxury sedan. Up to this point‚ BMW had been following their traditional method of designing automobiles. However‚ a project meeting was scheduled for that day to decide whether to change to a new approach for prototyping the cockpit of the new 7-series. This new approach would result in higher tooling costs and longer lead times‚ but the team felt that it could drastically

value of r that minimizes this by taking the derivative‚ stetting it equal to 0‚ and solving for r. Use that to find h. You’ll find that the dimensions are different from an actual soda can‚ but I’m sure you can think of why this is the case. THE MATH PROBLEM: The surface area of a cylindrical aluminum can is measure of how much aluminum the can requires. If the can has a radius r and a height h‚ its surface area A and its volume V are given by the equations: A=2(pi)r^2 + 2(pi)rh and V=

Introduction: The Fibonacci Series The Fibonacci Series is a sequence of numbers first created by Leonardo Fibonacci (fibo-na-chee) in 1202. It is a deceptively simple series‚ but its ramifications and applications are nearly limitless. It has fascinated and perplexed mathematicians for over 700 years‚ and nearly everyone who has worked with it has added a new piece to the Fibonacci puzzle‚ a new tidbit of information about the series and how it works. Fibonacci mathematics is a constantly
